Centralized controlling system for several kinds of working time in automobile manufacture

Abstract

Abstract PURPOSE: To control several kinds of device normally when a reference oscillator gets out of order by a method wherein an auxiliary oscillator oscillating substitute reference signals is worked by abnormality detecting signals. CONSTITUTION: When a reference oscillator 3 is normal, a frequency divider 2 divides reference signal frequencies from the reference oscillator 3 and draws fixed functioning signals to vehicular devices 1. When the reference oscillator 3 is abnormal, an alarm device 5 gives alarms by the detecting signals of an abnormality detector 4 while an auxiliary oscillator 6 outputs substitute reference signals, and the frequency divider 2 divides the substitute reference signal frequencies and introduces fixed functioning signals to the vehicular devices 1. Thus, the every kind of vehicular device 1 can function at all times on the basis of appropriate functioning signals regardless of the normalcy or abnormality of the reference oscillator 3.
